Bug 17022

System Environment:
--------------------------

--Platform:T61(965GM) or Compaq 6530b(Cantiga) openSUSE11.0-GM
--Architecture(32-bit,64-bit,compatiblity):32
--2D driver:2008Q2-RC3
--3D driver:Mesa7.0
--DRM:1.3
--Xserver:1.4.0.90
--Kernel:2.6.26
--Display connector:LVDS

Bug detailed description:
--------------------------
If we use EXA accelmethod, open news.sina.com.cn(which will use much buffer) by
firefox, this will cause firefox crashed. 
However using XAA, it will be OK.

Error:
Header value = 'Content-Type'
Header value = 'Content-Type'
The program 'firefox' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadAlloc (insufficient resources for operation)'.
  (Details: serial 7679 error_code 11 request_code 53 minor_code 0)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the --sync command line
   option to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)

Reproduce steps:
----------------
1) Add option "AccelMethod" "EXA" in devices section of xorg.conf
2) enter X windows, and open a terminal
3) firefox
4) type http://news.sina.com.cn (this website will cost much more buffer or memory)
